Loop 1, MoPac Expressway, Austin, Texas

An image of the new express lanes on Loop 1 in Austin. According to early reports, traffic volumes on the new tolled express lanes are above projections.
There were a total of 29,624 transactions on Wednesday. 15,830 northbound and 13,794 southbound. Both exceeded projections.

Southbound, the highest toll on Wednesday for a full length trip from Parmer Lane to Downtown was $4.64 and was in place for 8 minutes starting at 8:49 a.m. The average toll for that trip between 7:30 a.m. and 8:30 a.m. was $1.92

Northbound, the highest toll for a full length trip was $4.96 and was in place for 7 minutes starting at 5:21 p.m. The average toll for that trip between 4:30 p.m. and 5:30 p.m. was $2.29.

An important thing to note from this information, is that if you have the ability to shift your travel time just slightly, it can save you money!

We've also observed that travel times have improved significantly for all drivers on southbound MoPac during morning rush hour.

So much traffic

And I guess that most of that drivers have no other people on their passenger seats.

Anyways, what is the rail on the center? Only for freight trains?.

Yes, Loop 1 is called the Mopac Expressway. This name is derived from the Missouri Pacific Railroad.

California Highway 46. These photos look westerly as the highway progresses through the San Andres Fault Zone west of the Central Valley.

crazy to see that much traffic at the time. I'm so used to thinking that cars were relatively uncommon until post ww2, at least to the point where you wouldn't have high traffic facilities like that in rural areas.


Also, the rolling hills of central California are incredible. I love Cali in general for its nature - the entire state is incredibly beautiful.

NY-5, Utica

Governor Cuomo Announces Completion of $66.5 Million North-South Arterial Project in Utica

Governor Andrew M. Cuomo today announced the completion of the $66.5 million North-South Arterial reconstruction project in the City of Utica, Oneida County. The project is a record investment in the mobility and safety of the highest volume roadway in the Mohawk Valley and replaced the 55-year old elevated viaduct carrying Routes 5, 8 and 12 through the City of Utica with a grade-separated interchange that improves access in all directions. This was the largest project ever undertaken by the State Department of Transportation in the City of Utica.

The North-South Arterial is a main thoroughfare for the Mohawk Valley Region, passing through the western part of Utica. It provides vital connections to the NYS Thruway and the Adirondacks, facilitating the flow of business to and from the Utica area. It also connects the North SUNYIT Campus through Utica to other major highways in the area, such as New York State Routes 5, 8, 12 and 840.

The new highway, which is on a new alignment, is carried over Court Street at a new, grade-separated interchange improving access in all directions. This Single Point Urban Interchange opened in June, and its modern design is only one of a few operating in the state.

US 23, Michigan

A 'flex route' will open to traffic north of Ann Arbor, Michigan on Wednesday.
Gov. Snyder praises $92 million U.S. 23 Flex Route north of Ann Arbor

Snyder on Monday, Nov. 13, attended a press conference at a state rest area on U.S. 23 to discuss completion of the $92 million project. The project adds a third lane in both directions of the highway from Ann Arbor to Nine Mile Road, or M-36. It's expected to open to traffic on Wednesday.

The "Flex Route" is not a standard highway travel lane. It is an extra lane on the inside shoulder of the expressway that is only open during rush hour and times of heavy traffic. Overhead signals tell drivers if the lane is open for use.
Full report: http://www.mlive.com/news/ann-arbor/...ute_north.html

This was reportedly a cost-saving measure, a regular expansion would've cost some $ 400 million. Evidently there are several 'flex routes' planned in Michigan.

This is very similar to the Dutch 'plus lane', which is also a rush hour only, left shoulder lane. However the Dutch plus lane was built for environmental reasons, for some time it was impossible to expand freeways with a regular six-laning, so they built 'plus lanes' to circumvent some of the legislation. This is now a thing of the past.

I fail to see the advantage of such left-shoulder flex lanes. Why can't they be open all the time? You still have the right shoulder for emergencies.
It is an unnecessary waste of space in my opinion.

IIRC they're supposed to reduce induced demand by not generally increasing capacity but just preventing the worst jams.

If you want to reduce demand, just left people rot in traffic jams. Next time they will take another route. If you spend a lot of money building a lane, it must be used to the fullest, that's my opinion.

They claim that this lane is narrower, a proper expansion would've cost $ 400 million as opposed to the $ 92 million for this 'flex route'.

Unlike Europe, there is a tendency to construct left shoulders at wider freeways, so this will elevate the construction cost of an expansion project.

US 52

A new arch bridge across the Mississippi River opened to traffic yesterday. The new Savanna-Sabula Bridge is located at the Illinois-Iowa state line and carries US 52 traffic over the river. It replaced a 1932 truss bridge.

In the UK, these are called "Smart Motorways" and there are three types.

The first is Hard Shoulder Running. This is when the hard shoulder is opened at busy times to increase capacity. The speed limit is usually lowered from 70mph to 60mph and can be varied to 50mph or as low as 40mph depending on traffic conditions to try and smooth the flow. The limits are enforced by speed cameras.

The second is All Lane Running. This is when the hard shoulder has been permanently converted to become a permanent running lane. The speed limit is 70mph unless the signs are switched on where they can be lowered to 60mph, 50mph or 40mph. Again this is to try and smooth the flow of traffic. The limits are also enforced with speed cameras.

Thirdly there are sections that have permanent shoulders with the live lanes controlled by variable speed limits, with the aim of managing flows. Again lower speeds are enforced with speed cameras.

The oldest unmodified sections of motorways also have matrix signs that will post speed limits but these will be advisory usually if there is a hazard or to warn drivers of tailbacks. Hence, they are not enforced.

If a speed limit is shown in a red circle - an "order" sign under the Vienna Convention", it is a mandatory limit. Limits shown without the circle are advisory limits but these are used mainly on stretches that haven't become Smart Motorways.

More information here.

https://www.gov.uk/government/upload...nteractive.pdf

Smart motorway's are a concept for getting more capacity out of the same width of road. It is sadly widening on cheap and has led to many sections of Motorway being "upgraded" this way instead of full on widening with additional lanes and a shoulder. Many sections that were programmed to be properly widened are being upgraded to All Lane Running instead by converting the hard shoulder - a backward step in my opinion.

A key issue is breakdowns. CCTV cameras are sited so that Smart Motorways are fully monitored. Although emergency refuges have been provided, they are too far apart. So for example, if a vehicle becomes stranded on the motorway in the left lane (we drive on the left, remember!) because it could not make it to the refuge, the left lane (lane 1) has to be closed lane 2 is usually closed also to provide a buffer for safe recovery. Unlike conventional motorways with hard shoulders, this causes huge congestion, especially on the busiest section of motorways.

Mountain View Corridor

A 2 mile section of the Mountain View Corridor near Salt Lake City opened to traffic yesterday. It runs between 5400 S and 4100 S in West Valley City (orange on the map below).

The Mountain View Corridor is mostly built as an at-grade corridor, though only major intersections with a future interchange planned are at-grade, minor roads are grade-separated.

I drove across the old bridge. Narrow and steep but quite fun for a road geek.

Are they going to demolish the old bridge or maybe convert for pedestrian/cycling?

A while ago I've read they were going to give it away for free for anyone who had the means to relocate it to a different location. But they're now talking about demolition, so apparently there was nobody interested in a free deficient and obsolete bridge.

If you believe that, I've got a bridge to sell you...
